brcm2708: rename target to bcm27xx

This change makes the names of Broadcom targets consistent by using
the common notation based on SoC/CPU ID (which is used internally
anyway), bcmXXXX instead of brcmXXXX.
This is even used for target TITLE in make menuconfig already,
only the short target name used brcm so far.

Despite, since subtargets range from bcm2708 to bcm2711, it seems
appropriate to use bcm27xx instead of bcm2708 (again, as already done
for BOARDNAME).

This also renames the packages brcm2708-userland and brcm2708-gpu-fw.

+Subject: [PATCH] staging: bcm2835-audio: Drop debug messages in
+ bcm2835-pcm.c
+
+commit 055e1c330d04df87d4730a5db837161c11ddaafc upstream.
+
+These debug messages worsen the code readability a lot while they give
+little debuggability (which we already have via tracing, in anyway).
+
+Let's clean them up.  This allows us to reduce the
+snd_bcm2835_pcm_lib_ioctl() function to be a direct call of the
+snd_pcm_lib_ioctl callback (like most other drivers do), too.
